[0006] "Shooting Mode Checking Process" of Patent Document 1 ( figure 2 S13) always starts, not according to need, so the efficiency is low
Also, in Patent Document 2, "Shooting Mode Automatic Setting" ( Figure 4 S112) is only a one-time action after the release button is pressed halfway, and it is impossible to stably set the appropriate shooting mode corresponding to the shooting scene that may change at any time

no. 1 approach

[0041] figure 1 It is a schematic block diagram showing the structure of the digital camera 1 of the present invention. The digital camera 1 converts image data obtained by photography into an image file in the Exif format, and records it in a recording unit 70 such as an external recording memory that is detachable from the main body.

[0042] As the operating system of the digital camera, there are: an operation section 11 including an operation mode switch, a menu / OK button, a zoom / up and down arrow lever, left and right arrow buttons, a Back (return) button, a display switching button, a release button, a power switch, etc.; And the control circuit 74 which interprets the operation content of the operation part 11, and controls each part. The control circuit 74 includes: a CPU 75 for information processing; a ROM 68 recorded with programs for specifying information processing, thresholds for various judgments in firmware and programs, and other constants; RAM 69 for stor...

[0245] Figure 15 It is a flowchart showing the frame fluctuation checking subroutine of the second embodiment. This treatment can replace image 3 processing is executed. The execution of this processing is controlled by the CPU 75 of the camera 1 . A program defining this processing is stored in ROM 68 .

[0246] S201-S203 are the same as S21-S23.

[0247] In S204 , in the parameter change_measure of the RAM 69 , the value to which the weight E_AUTOSP_FRAME_CHECK1 corresponding to the first frame fluctuation check is added is set as a new change_measure. E_AUTOSP_FRAME_CHECK1 is stored in ROM68 in advance.

[0260] Figure 17 It is a flowchart of the main processing of the third embodiment. This treatment can replace figure 2 processing is executed. The execution of this processing is controlled by the CPU 75 of the camera 1 . A program defining this processing is stored in ROM 68 . In this embodiment, the frame change check is performed multiple times based on the frame change reference information (individual frame change check), and the frame change check result is stored as the frame change history, and the frame change check is performed based on the frame change history (the whole frame change check). change check).

[0261] S301-S303 are the same as S1-S3. However, in S302, the frame change history is also initialized.

Abstract

The invention provides an imaging apparatus and method for outputting stable results as necessary when recognizing scenes with a camera. If the result of scene recognition is unstable, then the output result will confuse the user. In consideration thereof, by combiningly performing processing for determining what type of scene a particular scene is and processing for monitoring whether or not a change has occurred from a recognized scene, it is now possible to perform scene recognition in an accurate and stable manner.

Description

technical field [0001] The present invention relates to an imaging device with a function of judging an imaging scene. Background technique [0002] In Patent Document 1, it is judged whether an actual shooting scene is suitable for a set shooting mode based on a digital image signal obtained by a CCD and an EV value. If the shooting mode is suitable, the digital camera performs shooting processing in this shooting mode, and records the shooting mode information in the header of the image data. If the shooting mode is not suitable, the operator confirms whether the setting is Shooting in the selected shooting mode, and then enter the shooting process, and the operator confirms whether to record the shooting mode information in the header of the image data, or to record the standard shooting mode information. [0003] Patent Document 2 discloses an automatic shooting mode setting camera that sets the shooting mode of the camera based on output information from face recogniti...
